[arch-general] ABS version of postgresql-libs does not match repo?

The PKGBUILD at /var/abs/extra/postgresql-libs has version 8.4.0-1 (a version that was in testing a little while back), while the version in extra is still 8.3.7-2. This seems very dangerous since it would be easy for a non-testing user to give themselves an unintended soname bump. I'm guessing this happens because that's both the trunk and extra version for this package in svn? Might it be worthwhile to backout revs 49331 and 49332, which have this change and nothing more? Or am I missing something here?
